On the one hand its one of the most functional watches existing in the market nowadays. Apple has done a great job devising this device. Its for professional sportsmen, for climbers, divers or just those who are into active lifestyle.
Durability is top, battery capacity is awesome too.
But shortly before presentation I waited that they would change the design a little bit. They look pretty much the same as the previous model released last year. Its a pity, but not a big deal.
